| name | sumsub-check-skills-version |
| description | Verify that the locally installed Sumsub agent-skills package is compatible with the published version before doing any Sumsub work. TRIGGER at the start of any task that touches Sumsub — Sumsub Dev MCP tools (mcp__Sumsub_Dev__*), KYC/AML workflows, applicants, checks, transactions, verification levels, verification links, questionnaires, fraud network, VASP lists, or anything Sumsub-related — so the user is warned before a stale skills package produces wrong results. Also use this skill when the user explicitly asks "are my Sumsub skills up to date / current", "is there a newer version of the Sumsub skills", or similar. Skip the actual update (the user runs `npx skills add SumSubstance/agent-skills --all` themselves) and skip any other Sumsub API or entity task — those have their own skills. |

Sumsub: Check Skills Version
Detects version drift between the locally installed @sumsub/agent-skills package and the canonical version published at https://api.sumsub.com/llms.txt, so that out-of-date skills don't silently produce stale or incorrect Sumsub behavior.
This skill's one user-visible deliverable is the headsup line. Running check_version.sh only computes it; the skill has not done its job until that line appears in your reply to the user. Treat emitting it exactly like emitting the result of any other tool call — not as an optional courtesy.
Two-phase protocol (this is how the heads-up actually lands)
Only your FINAL reply reaches the user, and you surface what is freshest in your context when you compose it. If you compute the heads-up first and then do a task, the task result becomes the freshest thing and the heads-up gets dropped. To prevent that, split the work into two phases:
Phase 1 — compute the verdict (before the task). Run check_version.sh. It computes the verdict and caches the rendered heads-up. Note whether a headsup= line was printed; do not write anything to the user yet.
Phase 2 — render LAST, then compose. Carry out the user's actual Sumsub task. Then, as your final action before writing the reply — after the task, after every other tool call — run:
bash ${CLAUDE_SKILL_DIR}/scripts/render_headsup.sh
Treat its stdout exactly like the result of any tool you must surface: if it prints a blockquote, that blockquote is the first line of your reply, verbatim, rendered as markdown; then the task answer follows. If it prints nothing, say nothing about the version. The render step is deliberately your last tool call so the heads-up is the freshest thing in context when you compose — that is what makes it survive into the final reply.
For an explicit "are my skills up to date?" question there is no other task, so Phase 1 already leaves the heads-up as the freshest output — just lead your reply with it; the Phase-2 render is a no-op you can skip.
When NOT to run the check
Do not invoke this skill, run check_version.sh, or mention Sumsub-skills version drift when:
- The user asks about non-Sumsub tools or vendors (Onfido, Persona, Stripe, etc.) — even if the topic is KYC.
- The user asks about generic package freshness (
npm outdated, pip list --outdated, etc.) for their own project — that is unrelated to the @sumsub/agent-skills npm bundle.
- The user explicitly says they are not asking about Sumsub.
Never append a "by the way, want me to check your Sumsub skills?" sidenote on unrelated answers.
Anti-pattern (npm outdated): ❌ "Want me to run sumsub-check-skills-version instead?" or mentioning agent-skills-version / llms.txt — the user's npm question is complete once you've summarized npm outdated. Stop there.
Anti-pattern (vendor comparison): ❌ Mentioning Sumsub skills version while comparing Onfido vs Persona. Answer only what was asked.
When to run the check
Run it once per session, before the first Sumsub-related action. Concretely:
- Before calling any
mcp__Sumsub_Dev__* tool for the first time in this session.
- Before walking the user through any Sumsub workflow (creating an applicant, requesting a check, reading a transaction, building a verification link, etc.).
- When the user explicitly asks whether their Sumsub skills are up to date.
Do not re-run the network check (check_version.sh) within the same session — repeated curls add latency without value. The Phase-2 render_headsup.sh step does not re-check; it only re-emits the cached verdict, and it is mandatory every time you produce a Sumsub answer in a session that found drift.
The check is non-blocking only in the sense that you do not pause or wait for the user before continuing — it does not mean the heads-up is optional or skippable. Follow the two-phase protocol above, then proceed with the user's task in the same reply.
How to run the check
bash ${CLAUDE_SKILL_DIR}/scripts/check_version.sh
It prints up to four key=value lines on stdout:
local=1.0.1
remote=1.0.2
status=PATCH_BEHIND
headsup=> ⚠️ **Sumsub skills update available** — you're on **1.0.1**, latest is **1.0.2** (patch). Run `npx skills add SumSubstance/agent-skills --all` to update.
local — installed version (baked into references/version.txt at publish time).
remote — canonical version parsed from the agent-skills-version: line of the canonical llms.txt.
status — the verdict (see below).
headsup — present only for non-silent verdicts; the exact markdown line to surface. Don't emit it from here — Phase 1 just caches it; the Phase-2 render_headsup.sh step re-prints it (as a clean blockquote) when you're ready to compose. Never echo the local=/remote=/status=/headsup= keys themselves.
The remote URL is https://api.sumsub.com/llms.txt. No credentials needed — it's a public static file. Override with the SUMSUB_VERSION_URL environment variable for testing.
How to handle each verdict
The headsup text is produced once, by Phase 1, and re-emitted by Phase 2's render_headsup.sh; you never hand-write it. Whatever the render step prints becomes the first line of your reply, verbatim. If it prints nothing (silent verdict), say nothing about the version. The heads-up is shown once per session.
For reference, what each verdict means:
status | headsup present? | Meaning |
|---|
UP_TO_DATE | no | Installed version matches the published one — stay silent. |
PATCH_BEHIND | yes | A patch release is available — surface the line, then proceed. |
MINOR_BEHIND | yes | A minor release is available — surface the line, then proceed. |
MAJOR_BEHIND | yes | Significantly behind; behavior may have changed — surface the line, then proceed. |
AHEAD | yes | Local is newer than published (likely a dev build) — surface the line, then proceed. |
UNKNOWN | no | Remote unreachable or unparseable — stay silent, never block the user. |
Important: never block the user's request because of the verdict, and never show the heads-up more than once in the same session — if you've already shown it in this conversation, don't repeat it.
Worked example — implicit trigger
The most common case: the check runs as a background step before some other Sumsub task, verdict is non-UP_TO_DATE. Order of operations:
- Phase 1 — run
check_version.sh (verdict PATCH_BEHIND, local 1.0.0, remote 1.0.1; heads-up cached). Write nothing yet.
- Do the task — look up the transaction.
- Phase 2 — run
render_headsup.sh as your last action; it prints the blockquote.
- Compose the reply: blockquote first, task answer after.
User: "look up sumsub transaction 65a3… — what risk score and which rules fired?"
Your reply:
⚠️ Sumsub skills update available — you're on 1.0.0, latest is 1.0.1 (patch). Run npx skills add SumSubstance/agent-skills --all to update.
Transaction 65a3…: risk score 78 (RED), 2 rules fired — …answer the actual request here…
Notes
- The check needs no API credentials — the canonical
llms.txt is a public static file.
- The local version lives in
references/version.txt and is bumped together with public/package.json and public/skills.json on every release.
- If the canonical source moves (host change, or migration to a different file shape), set
SUMSUB_VERSION_URL to the new location; the script accepts an agent-skills-version: line (preferred), a JSON "version" field, or a bare version: line.
